NICKING DEVICE FOR CIGAR-WRAPPING MACHINES.

' To all whom it may concern in nicking mechanism for 'cigar wrapping machines, and is particularly adapted for use in connection with automatic cigar making machines.

- In cigar wrappingmachines, it is necessary that the wrapper be nicked at the time the flag end of the wrapper is wound about the head of the cigar. Various mechanisms have hereto-fore been used for this purpose but they were all more or less complicated and troublesome.

The main object of the present invention is the production of a nicking device for cigar machines extremely simple in construction and more efficient in operation.

A further object of the invention is the production of a cigar wrapping device having a tension plate one end of which is downwardly curved adjacent the head of a cigar in the wrapping device, this downwardly curved end being slotted so that a rotary nicking device having widely separated nick ing knives can operate at high speed through said slot at the head of the cigar in order to nick the wrapper as it is drawn down over the curved end of the tension plate.

With these and other objects not specificallymentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying drawings, which form a part of this specification and in which like characters of reference indicate the same or like parts, Figure 1 is a front elevation of a device constructed in accordance with the invention. Fig. 2 is a side elevation of the structure shown in Fig. 1. Fig. 3 is a fragmentary plane view of a part of the structure shown in Figs. 1 and 2. And Figs. 4 and 5 are detail views of the rotary nicking cutter shown in the other figures.

, In carrying the invention into effect, there Specification of Letters Patent.

Patented June 27, 1916.

Application filed May 3, 1915. Serial No. 25,382.

is provided means for rotating a cigar bunch and delivering a wrapper thereto, and a wrapper nicking device comprising a plurality of widely separated nicking knives, and means for successively moving said knives at high speed past the head of a cigar lying within the bunch rotating means and into the path of the flag of the wrapper as it is wound about the bunch. In the best c0n structicns, the widely separated nicking knives are mounted upon, or formed upon, a

disk rotating at high speed, and there is further provided. a tension plate having a curved end over which the wrapper is drawn as it is wound about the cigar curved head being provided with a slot through which the nicking knives work. The above elements maybe varied in construction within wide limits.

The device selected to illustrate the invention is but one of many possible concrete embodiments of the same, and the invention therefore is not to be restricted to the pre cise details of the structure shown and described.

Referring to the drawings, 6 indicates the main roll and 7 indicates the cooperating rolls of a group of rolls forming means for rotating a cigar bunch. There is further provided a suction wrapper support marked 8, the function of which is to support and deliver a wrapper to a cigar bunch lying within the group of ro particular construction of the rolls 6 and 7, and of the wrapper support 8, is well known in the art and further description thereof is unnecessary to a complete understanding of the invention. Such further description is therefore omitted herefrom in the interest of brevity. The rolls 6 and 7 are suitably supported in a casting 9, and to this casting is secured a shear plate 10 at the point where lies the head of a cigar within the group of rolls' 67, and is clearly. shown in Fig. 1. Cooperating with this shear plate is a disk 11 having a plurality of nicking knives 12 formed thereon or affixed thereto. Thedisk 11 is fast upon a shaft 13 suitably journaled in bearings formed in a bracket 14:, which bracket is pivoted at 15 to a second bracket 16, this second bracket being secured to the main frame 17 of the machine. Threaded through the bracket 14L are two screws 18 head, this lls 6-7. The Y and 19, the screw 18 bearing against the main frame 17 and the screw 19 hearing against the bracket 16. By means of these screws, the bracket 14:, and of course the shaft 13 and disk 11, may be adjusted in a direction transverse to the axis of a cigar bunch lying within the group of wrapper rolls. Upon the outer end of the shaft 13 is fixed a pulley 20, over which runs a belt 21 deriving its motion from a large pulley 22 fixed upon a shaft 23 which is one of the main shafts of the machine. The shaft 13 and the disk 11 rotate at high speed, and the nicking knives 12 are widely separated on the periphery of the disk 11 partly be cause the speed of the nicking knives is greatly in excess of the speed of the wrapper being wound about the cigar head, and partly to prevent displacement of the flag of the wrapper during the head wind ing operation that would occur if the nick ing knives were near enough to produce a fan-like action that would lift the wrapper flag from its normal position and thereby prevent proper nicking. A belt tightening pulley 26L is provided for the belt 21 and is carried upon an arm 25 suitably clamped upon the pivot 15 before referred to.

Cooperating with the bunch rolling means and wrapper delivering means is a tension plate 26 having one end; that is, the end adjacent the head of the cigar, curved downwardly at 27, this curved end being provided with a slot 28 through which the nicking knives 12 can operate. The purpose of the curved end 27 of the tension plate is to provide a suitable support for the flag of the wrapper as it is wound about the cigar head and after it leaves the wrapper support 8. Thewrapper flag carries a small quantity of paste upon its under surface, applied thereto in any one of the various ways known in the art, and this pasted surface dragging down over the curved end 27 of the tension plate tends to keep the flag properly stretched as it moves downwardly over said curved end. Furthermore, it tends to hold the flag of the wrapper against displacementas the nicking knives 12 move through the slot 28 and cooperate with the shear plate 10 to nick the wrapper at the cigar head. Apart from this curved end, the tension plate 26 is of a type well known in the art and is moved in and out of operative position by means of a lever 29 fulcrumed at 30 and controlled by a cam 31 in a manner well known in the art. The tension plate is raised and lowered by means of an adjustable connecting rod 32 and a bell-crank lever 33 controlled by a cam 34 in a manner well known in the art. Since the particular construction of this tension plate controlling mechanism is well known in the art, and since further description thereof is unnecessary to a full understanding of the invention, such further description is omitted herefrom in the interest of brevity.
